What would cause oil to leak into the antifreeze reservoir?

Consider if it is engine oil or transmission oil or power steering oil. Transmission oil or power steering oil would indicate a bad radiator. Engine oil could be a bad radiator also if the radiator includes an engine oil cooler ("extra cooling") but usually indicates an intake or head gasket leaking.

Answer

Your symptoms are indicating a possible head gasket problem. If you have oil in the water, you may have water in the oil. Pull out the dipstick or take off the oil fill cap and look for the unusual condition of FOAMY oil. You may also have exhaust gas in the water which can also be checked by a mechanic. Be prepared for the expense of a head gasket or possible engine replacement.

answer

if you have oil in coolant, you have a cracked head or a cracked block your mechanic will do a compression test to determine what it is either way it is not cheap fix unless you can do it yourself

ANSWER

you may have a blown head gasket, or cracked head , or cracked block

Answer

It could be a number of things listed above. However I had this issue with my 3.1 V6 GM engine. I had oil in the coolant, and it turned out to be a failed Intake Manifold Gasket. It is best to take it to a repair shop and let a professional handle it unless you are mechanically inclined. If it is an Intake Manifold Gasket your looking at a ball park figure between 400 to 900 dollars. Think of it this way, would it be more beneficial to fix your current car? Or to go and put a down payment on a new one and get stuck with payments for the next 5 years?

its a BLOWN HEAD GASKET, OR A CRACKED HEAD or CRACKED BLOCK one of the three.....

It seems everyone assumes that you are talking about a gasoline engine which for the most part they would be right: radiator oil/trans-fluid internal cooler, intake leak or head gasket. If you are talking about a diesel engine, could also be oil cooler o-rings, cylinder liner o-rings, failed e.g.r. cooler, etc.

i think its funny that i have that same problem with my 3.1 v6 gm motor and my friends grandmom had the same problem lol and there is oil in my reservoir alott and if u want to know if u bad head gaskets u wont be able to see people behind u because ull be pouring white smoke out of ur exhaust, and whoever said water is heavier then oil is retarted its less dense then water yes but not heavier its hard to tell what the exact problem is so first things first id do the intake manifold gasket one because the part is cheap and to its not exactly ripping ur motor apart

yes lets tell this person to fix there exhaust manifold because that takes care of his oil & water problem. the person that feels not pulling an engine apart, how do u fix a a hungry stomach. now this person has oil in the water not an exhaut minifold problem geeezzzz some people.....

How do you back flush the radiator cooling system on a Ford Taurus?

How Much Coolant?

Since there are so many variables - year of car, engine size, etc. it is best to refer to the Owners Manual for your specific car to determine cooling system refill capacity.

See "Related Questions" below.

If you are environmentally concerned then you need to take it to a repair shop that has a flushing machine. If not, any parts house has the chemicals. Just follow the directions on the container.

Purchase a Prestone flush kit, a container of radiator flush, and new antifreeze at a automotive parts store. There are directions on the flush kit package. What you will be doing is adding the chemical to your cooling sytem then inserting a flush tee into a heater hose and back flushing the system using your garden hose. Works very good.

To let the coolant out:

First, take off the black plastic guard underneath the front of the car. It's being held in place by a bunch of small screws.

After removing the plastic cover, you should be able to see the radiator, and at the bottom corner of the radiator on driver's side, you'll see a white plug/nut. I used a 19mm key for that.

The plastic screw does not come completely off, just unscrews far enough to let all the coolant out.

To let all the coolant out, your engine should be cool. Take the top off the coolant reservoir, place a bucket under the car and unscrew that white plug.

At this point, either fill it back up with coolant or follow the directions on the bottle of coolant flush you bought.

The easiest stress free way is to go to Wal-Mart and get a Flush Kit that hooks up to your garden hose.

Buy a flushing kit at Wal-Mart or auto parts store comes with instructions, fitting, and adaptors.

back flushing is old country... if she's plugged replace her.

There is a small white plug underneath the radiator. If you're looking at the car from the front, it's on the right. Unscrew it (hopefully you do it when its cold) and let it drain. From there, you put a hose in the reservoir and let it run through the system for a few minutes, keeping the white plug off. Then shut off the hose, put the white cap back on, and put in the right quantity of regular antifreeze.

Be prepared to bleed trapped air from the car's cabin heater system - you'll know you need to do that if the car's heater fan doesn't blow hot air after the engine has reached its normal running temperature!

there are two hoses coming out of your fire wall one is located on the passanger side and the other is located on the drivers side. it is very easy to do with just a pair of piers. remove the hoses with the pliers they are connected with a self clamping clamps. then using a garden hose connector that i purchased at home depot $1.99 connect it to the drivers side hose protruding from the firewall, then connect the water hose to the connector and turn the water on and let it run for about 5:00 minates or utill the water is clear comming out of the passanger side fire wall. simple..........hope this wass helpfull

Are there cars that run without radiators?

I highly doubt it, a radiatior keeps your car from over heating so no radiator and your engine might explode. The early Volkswagon beetles were air cooled, no radiator.

How much does radiator repair cost on average?

Well radiator repair will depend on the damage or replacements needed to fix the radiator. Thus, no average cost is really available. However, if it is only minor repair I would think that it should only cost $50 dollars for parts and then whatever the repair man is charging for labor.

Why radiator called radiator?

Because it transfers (or radiates) heat from coolant or whatever it is cooling.

Can a hole in a radiator be patched?

Modern radiators are not made to be repaired. Depending on where your leak is, you may be able to patch it. Radiator Stop Leak additives usually clog up the entire cooling system and cause more repair costs than they claim to avoid.

The best solution is to buy and install a new radiator.

Why is low radiator warning light on in 2000 Intrigue even though coolant reservoir is at proper level and not leaking - what is burping procedure?

Answer low radiator light onProbably a bad low coolant level sensor.

Sensor is located under the thermostat housing. Frequent problem with the Olds Intrigue

AnswerThe sensor for this vehicle is built in to the coolant reservoir. So just swap out the sensor? Not on this vehicle; the sensor isn't sold as a separate unit (darn it). You must purchase a new coolant reservoir, which includes a built in sensor. Multiple internet suppliers sell these reservoirs for $70 (including shipping).

Where is the drain plug for the radiator in a 2000 Dodge Dakota?

I think its at the very bottom right hand corner of the radiator. It is a small plug looking jobber. Access is very very tight. Basically, lift the hood, take a flashlight and look along the drivers side of the radiator at the bottom. You'll find it right below a small nipple looking jobber.

---

That's pretty much where mine is on my '02, but I have a small & short hose that connects right above and below it. I disconnected both ends of the hose to gain access to the drain plug for the duration of the radiator drain without ill effect.

Can you have a radiator crack welded?

Yes, it can be welded, depending on the location of the crack.

Some radiators are repairablbe, depending on the construction of the radiator. Older style all-brass/copper radiators can be soldered (not welded) if the leak area is accessible and the surrounding metal is strong enough. Some newer style plastic tank/aluminum core radiators can be repaired if the leak is at the joint between the tank(s) and the core, while others cannot. The plastic tanks themselves and the aluminum cores cannot be reliably repaired.

How do you fix a leaking radiator petcock?

Petcock FixHere are answers and opinions from FAQ Farmers:
  • First off, don't open a Durango petcock. If you already did there are replacement ones available after market. Another solution is to get it dry and silicone it in place, let it dry (24 hours), fill your system back up.
  • Plastic petcocks can be replaced by first removing the radiator from the vehicle. Now remove the stripped drain plug, then use an ice pick to remove the retaining clip inside the hole that the plug screws into (this is the part that usually fails). New plugs can be purchased at the dealer or NAPA....Next, unscrew the retainer clip from the new plug. Install the retainer clip and make sure it locks into place....be sure the retainer clip fits properly in the hole as each brand is different. In cases where the radiator is not the original, you may have to get a replacement drain plug from the aftermarket dealer that sells that brand radiator. Finally, screw the new plug into the hole using vaseline on the rubber gasket to help it seat tightly without having to overtighten the petcock. Better to leave it snug and then pressure test it for leaks and tighten it if necessary than to overtighten it. The stress from overtightening it may not damage it right away....it will fail when it gets hot a few times and under pressure....then it will dump all the coolant in a hurry. Something else to think about...usually this failure comes from overtightening or coolant contamination causing the plastic components to weaken and fail. Flush cooling system and check for oil or other contaminants.

If these petcocks are opened properly, there should not be a problem. Too many people just yank and twist on them causing unnecessary damage. If it does come out or leak, good old Teflon pipe tape works just finer.

How would get an air bubble out of the radiator?

Don't worry about it, just close the lid and the automatic filler will prime it eventually.

Most newer cars are self-purging. Keep coolant in the overflow tank and it will 'burp' out the extra air once the engine comes up to temperature. When it cools, the system will suck coolant out of the overflow tank to make up for the air that got 'burped' out. You'll know it is working because the coolant level in the overflow tank will drop.

Why would the radiator fan be the only thing to work?

Answer

The fan is meant to cool the radiator even after the car has turned off. Some vehicles have a heat type sensor to activate when the fan should "kick" in, others just automatically intermittantly run for a few minutes when turned on or have a set time for after it's turned off. Maybe when you did the wiring you inadvertantly disconnected something necessary to the start up of the vehicle. Sounds like you installed the fan to work properly so I would just concentrate on what wiring you were near when you put it in...something simple might've come off or loose.

Answer

I found the problem to be a poorly connected ground. After cleaning the plug the housed the ground; my problem was solved.

Greatestmind weighing in on this. Now it seems like you are saying your fan works fine but the coolant still overheats. If this is the case check your thermostat, and hope your water pump is working properly. Feel the inlet and outlet hoses on your radiator after about 5 minutes of engine running, both should feel hot to the hand.

Why is a car overheating even after changing the water pump and the radiator?

Always should replace thermostat at same time; if this was not done, do so. Rust and gunk in the cooling system from a corroded radiator will often jam and damage the thermostat. Conversley, sometimes a corrding thermostat sets of the entire process by both stricking and by sending hicks of rust to the other cooling system components (radiator and water pump). After engine idles for a while (but prior to overheating) gently squeeze the large hose attached to the top of the radiator. Is it getting warm? If not, the thermostat is likely not working. The thermostat should click and open the route for the top radiator hose, when the temp gauge is no farther toward "H" than at or just below the halfway mark, or just above, on most vehicles. Once the thermostat opens up the route for the upper radiator hose, the temp gauge should fall quickly. If the thermostat wasn't replaced, appears to not be functioning, and is easily accessible and visible, tap it with a hammer (not hard enough to damage it)and see if it becomes unstuck. If your vehicle has an electric fan, make sure it is coming on after a few moments. If it isn't, check that its fuse is OK, that the wire connections are solid, then check that the fan relay is not burned out. A heat sensor sending unit which controls activation of the electric fan could also have failed. In some 60's vintage vehicles, one could often stop overheating by replacing the stock 4-bladed fan with a 5-bladed fan. If you have an automatic transmission that is routed through your cooling system, and you've tried everything possible to correct overheating, your tranny may be on its way out. The problems your tranny may be having having operating normally could be effecting the engine temp. I agree with the changeing of the thermostat , Here is one more sug your radiator cap is not maintaining proper pressure get it pressure tested IF YOU DIDN'T CHANGE THE RADIATOR CAP WHEN DOING ALL THAT OTHER STUFF, GO AHEAD AND CHANGE IT. IF THE OLD ONE IS BAD IT WON'T HOLD THE PROPER PRESSURE AND THE COOLANT CAN BOIL= OVERHEATING! patricklaw1957@yahoo.com Check the fan to see if it's running. If the engine heats up and the fan isn't going, the fan motor is shot. If you have tried everything else and you are still having overheating problems you might have a bad head gasket. I didn't see what type of vehicle you were working on. I had a 1988 Dodge Caravan. I replaced everything in the cooling system including putting an oversized radiator in. The problem turned out to be a bad head gasket. I never observed any oil in the radiator. If the thermostat was replaced and water pump and radiator as you say then there are only a couple things that it can COMMONLY be.It always seems to me that people like to take out the engine before replacing the spark plugs.Take theese words of advice(alot of people over analyze things)99 percent of the time it's the easy stuff!your problem is probably the radiator cap.If it is not holding the proper pressure it will overheat.cost is about 4.95. could be bad head gaskit

Where is the radiator drain plug on a ford windstar?

The drain valve is on the back/bottom of one side of the radiator. If you're facing the van, it's on the driver side. You have to go under the van. If you raise it, use jackstands. When you're under the van, on the driver side, on the back of the radiator, near the bottom, you'll see the drain valve. It should be directly under the battery tray.

To open the valve, you'll need an Allen wrench. Once the valve is open, open the radiator. The radiator cap is on the coolant reserve tank, not on the radiator.

New AnswerYes there is a drain at the bottom of the radiator. It is located on the bottom corner of the radiator, drivers side, facing in the direction of the engine. You will have to raise the front of the van on ramps or jackstands to be able to get to it. It looks like a white plastic bolt and you can loosen it by turning it counter-clockwise with a wrench. Be careful when reinstalling it that you don't accidentally over tighten it or you might strip the threads.
